One entrepreneur is brewing up a way to make coffee "smart."
"We have smartphones, smart cars, smart water and now, with VitaPerk, you can smart your coffee," VitaPerk founder Brad Kifferstein tells CNBC.
Each packet of VitaPerk packs 15 vitamins and minerals into its powder-based supplement. It dissolves in coffee. Kifferstein says it's the most innovative product to hit the coffee market since the Keurig K-cup.
